The paper addresses the issue of achieving context-aware, adaptive multiparty sessions in a heterogeneous system by illustrating how to add elements of adaptivity and context-awareness to the session management functionality of such systems. The effective usage of situation/context information can lead to context-aware content casting, especially context-aware, adaptive multicasting. Therefore, regarding the multicast service, the key functionality of the enhanced session management is to create network subgroups based on network information as well as general user and environment context information to the extent that these are considered necessary for forming network-efficient groups, and in turn communicating the characteristics of these subgroups in the form of content stream descriptions to the media delivery function for obtaining the appropriate content for each subgroup.
